The long-standing champ in the hybrid segment, the 2018 Toyota Prius makes few changes to its proven formula.

Four trim levels are available on the 2018 Prius and are literally named One, Two, Three, and Four. One signifies the entry-level grade, while Four is the best-equipped. Three Touring and Four Touring trims are also available, which include minor option differences not found in the regular trims.

A 1.8-liter, 4-cylinder, Atkinson-cycle engine is found in the Prius. It combines with two electric motors to deliver an EPA fuel-efficiency rating of 52 mpg in combined city/highway driving.

Changes to the 2018 Toyota Prius:

What We Think

While the Toyota Prius remains the best-selling hybrid vehicle on the market, it’s winning by default at this point. Even with little competition, the Prius’ sales numbers have dropped significantly since it was redesigned for the 2016 model year. While blame may be placed on either a polarizing design or a growing number of competitors, the Prius’ decade-long streak of selling over 100,000 units per year ended in 2016, and sales have continued to decline.

Though the 2018 Toyota Prius remains an excellent choice for those shopping for a hybrid, many potential customers are realizing they have other options in the segment. It would be foolish of Toyota not to recognize this, and it would behoove them to implement necessary changes in order to keep the Prius ahead of the competition.
